Q:Hydraulic principle: Hydraulic transmission is also called volume hydraulic transmission, is liquid as the medium, the transmission device to transmit energy and control the use of liquid pressure energy and kinetic energy. Usually the liquid medium using the hydraulic system with the remaining liquid pressure energy is called hydraulic oil.

Q:What are the acceptance criteria for hydraulic cylinders?: China has published the hydraulic cylinder of the ISO standard (excluding seal standard 6), there are more than 20, as follows: ISO3320-75 hydraulic and pneumatic systems and components of a cylinder diameter and piston rod diameter of a ISO3321-75 metric series of hydraulic and pneumatic systems and components of a cylinder bore and piston rod diameter ISO3322-75 Inch series of hydraulic and pneumatic systems and components of a cylinder of a nominal pressure ISO4393-78 of hydraulic and pneumatic systems and components with a cylinder and a piston stroke basic pressure ISO4394-78 hydraulic and pneumatic systems and components of a cylinder diameter steel pipe processing conditions of ISO4395-78 hydraulic and pneumatic systems and components of a cylinder and a piston rod thread size ISO5597/1-80 type of hydraulic cylinder piston rod and a piston reciprocating sealing groove: Nominal dimensions and tolerances of 1 series ISO6020/1-81 -160bar series hydraulic single rod hydraulic cylinder - Mounting dimensions

Q:what to use, there is no suitable cylinder, the company's gas supply is not enough, my device does not have much pressure.The pressure of the air pressure is enough, but the air source is insufficient, and the suitable cylinder can not be selected, so the hydraulic station is used to control the cylinder, but there is no such device, and the friend who knows it tells the thanks!: Oh, my friend, in the hydraulic control system of the cylinder is certainly not good, because the sealing ring of the cylinder is not resistant to oil, and the pressure of the hydraulic system are generally larger, the cylinder wear large, recommended to buy several sets of cylinders can be customized, installation size according to your request, if need can contact I

Q:How do I calculate the flow rate of the hydraulic cylinder?: Hydraulic cylinder flow = hydraulic cylinder piston cross section * speedFor example: the cylinder speed of D10cm requires 10cm per secondThe hydraulic cylinder piston cross-section =pi * D * D, 4=3.14 * 10 * 10 4=78.5 / cm2Flow per second =78.5 * 10=785 ml =0.785 litersThe flow rate is =0.785 * 60=47.1 liters per minute

Q:Can the hydraulic cylinder change the nitrogen cylinder?: This estimate is not, first consider the seal hydraulic oil cylinder and the air cylinder design according to different media, sealing is certainly not the same, if the hydraulic oil cylinder into the cylinder may be sealed and lax circumstance.

Q:What is it used for? What kind of factory is likely to be used in general?: Hydraulic equipment, cylinders, cylinders are used in the principle of hydraulic transmission power, in particular, low aerodynamic pressure, hydraulic high. At the same time, the environment

Q:Why is the digital hydraulic cylinder not widely used?: 4, servo control system.Several of these are for reference only.A hydraulic cylinder is a hydraulic actuator that transforms hydraulic energy into mechanical energy and makes linear reciprocating motion (or swinging motion).The utility model has the advantages of simple structure and reliable work.

Q:What are the characteristics of the cylinder compared with the hydraulic cylinder?: Low pressure cylinder bore the same, but the working environment is clean, the hydraulic cylinder oil leakage problem

Q:What is the essential difference between hydraulic oil and lubricating oil?: Definition of hydraulic oil,Hydraulic oil pressure is the hydraulic medium used in hydraulic system with liquid pressure energy. It plays the role of energy transmission, system lubrication, corrosion prevention, rust prevention and cooling in the hydraulic system. For the hydraulic oil, should first meet the requirements of the hydraulic device in the operating temperature and the starting temperature of the liquid viscosity, the viscosity change of oil is directly related to hydraulic operation, transmission efficiency and transmission precision, but also oil viscosity temperature properties and shear stability should meet the needs of different uses of the proposed.Definition of lubricating oilLubricating oil is used in various types of machinery to reduce friction, protection of machinery and processing parts of liquid lubricants, mainly from lubrication, cooling, rust, cleaning, sealing and buffering.By contrast, some of the effects of hydraulic oils and lubricants are the same... But they differ in their environmental conditions and are higher than those for hydraulic fluids...

Q:What is the cold drawn cylinder of a hydraulic cylinder? How about his quality? Master, help! Thank you: Is the map in 4, the main advantages of the cold drawn pipe is the inner and outer dimension precision (tolerance) strictly, and surface roughness, roundness, straightness, uniform wall thickness, our company specializing in the production of hydraulic cylinder, the cylinder and the cylinder, the piston rod and its accessories, high quality and low price, welcome to buy
